ePTFE Reinforced PFSA Membrane for High-Performance PEM Electrolyzers

Our ePTFE Reinforced PFSA Membrane, also known as a cation exchange membrane, is specifically designed for high-performance PEM electrolyzers.

This advanced membrane separates the anode and cathode compartments in PEM electrolyzer stacks, which consume electricity and DI-water to generate hydrogen and oxygen gases.

The membrane comes in 50, 80, and 110-micron thickness which allows for high current densities while maintaining mechanical robustness, essential for demanding electrolyzer applications.

Experience the superior performance and durability of our ePTFE Reinforced PFSA Membrane for your PEM electrolyzer applications and beyond.

Key Features

Enhanced Durability: The ePTFE structure significantly extends the operational lifetime of the membrane by mitigating swelling-related stresses, making it far more durable than unreinforced membranes.

High Performance: Ideal for PEM electrolyzer stacks, this membrane supports very high current densities and long operational lifetimes.

Chemical Stability: Made from chemically stabilized perfluorosulfonic acid (PFSA), it offers lower fluoride ion release, ensuring superior chemical resistance and durability.

Protective Cover Film: Each membrane features a cover film on one face to safeguard it during shipping.

Ready to Use: Our ePTFE Reinforced PFSA Membrane is shipped ready for immediate use, with no pretreatment steps required, ensuring a seamless integration into your PEM electrolyzer systems.

Technical Specifications

Thickness: 50 microns

Material: Chemically stabilized perfluorosulfonic acid (PFSA)

Form: Shipped in the acid (H+) form

Reinforcement: Microporous ePTFE, providing a 3-D porous structure for PFSA impregnation via the solution cast method.

Density, g/cm³: 2.0±0.05

Ionic Exchange Equivalent Weight, g/mol: 900-1000

Proton Conductivity, mS/cm: >70
